gears in my '76 truck
 

I decided to make a muscle truck :drive: and was wondering about the gear ratio in rear. Is it optimized for towing and not speed? If it is what should i be looking to replace them with? TIA for any help :)

3.73 gears is what i got in mine and i can still get on the highway and roll out

Do you have a ten or twelve bolt rear?
What gears do you have now?

I have a 10 bolt with 2.73 gears... it's great for the highway and daily driving.

From what I've heard 3.23 or 3.73 gears give good performance without suffering on the road. Somebody correct me if I'm wrong.

I got 3.42's in mine but im thinkin about bumpin up to 3.73 for the extra pep
